Be it known that I, WILLIAM lxnaosn, a

citizen of the United States, and residentof Milwaukee, in the county of Milwaukee and State of "Wisconsin, have invented certain new and useful Improvements in Box-Protectors; and I following is a full, clear,'and exactjdescrrP- tion thereof. T

My invention refers to sk letoncontain ers or bottle crates, rectangular in form and having wooden side closed in Patent No, 9331St, dated September 7th,.l909. Crates of this general character are adapted to travel or slide upon conveyers and the bottom edges thereof, are subjected to severe wear, which causes quick deterioration, and thereby renders the crates, otherwise in'good condition, impractical for use. 3

My present invention has for its object to provide means for preventing the wear upon the bottoms of such crates, incidental to their uses as stated above. Specific objects of the invention are:

To provide the lower side wall edges with metallic shoes or runners whereby said edges are protected;

To provide grooves in the edges of thefor the reception of metallic run-' ners, whereby they will be held in position withrelation to the side walls, but will project below the bottom edge to thus eliminat wear;

To provide suchrunners in the form of wire strands, partly embedded in the bottom edges of the crate side walls, having upturned ends at acute angles and fitted in corresponding sockets, whereby the runners are held in position under more or less spring tension.

lVith the above and other in view, the invention consists in certain peculiarities of construction and combination of parts as are hereinafter set forth with reference to ings.

In the drawings:

Figure 1 represents a fragmentary view of a crate, partly in section, having. attached thereto a metallic shoe or runner embodying the features of my invention.

Fig. 2 is an inverted plan view of the same, and

Fig. 8 is a cross section through one of side wall Specificatiomof Letters Patent.

the side walls showing the runner embedded Referring by characters to'the drawings,

A--A represents wooden panel end walls of a rectangular crate,having side walls The endand'side walls in this instance are longitudinal grooves 1, into which grooves are fitted wirestrands 2, preferably round in cross section, the same constituting runners, The wlre strands, as best shown in Fig. 3, are of such cross sectionalarea with respect to their grooves that the lower edges of said strands pro ect below the bottom edges of the panels, so as to form protecting I runners therefor. g

As best shown in Fig. l, the longitudinal grooves 1 extend approximately throughout the length of the panels B, and at the ends these grooves are intersected by upwardly extending, sockets 3, which sockets are dis posed at acute angles to the groove. The ends of the runners are turned upwardly to form anchor legs l, which legs are sprung into the sockets, andv owing to the fact that they are slightly compressed when inserted, the expansile force of the legs will tend to hold the runners rigidly in their assembled relation with the panels. g i In some instances, as shown inthe exem- Patented July-12,1921. Appncation an NoVemhenZZ, .1920. seriatm i fl h if plification of'myinvention, the corner irons C may be provided withoutwardly extended flanges c-'0, which flanges overlap the bottom edges of the juxtaposed side and end panels. The arranged to fold over the end portions 4 of the runners, whereby they are positively secured in their nested position with relation to their panel grooves. Obviously,

crates equipped with these runners will be protected against wear, due to their hard and the life of'such crates is mate- It will also be observed that owing to the simple arrangement whereby the runners are attached, that crates equipped with them can be manuusage,

factured at a minimum cost, which is a ma .terial factor in marketing an article of thls character.

\Vhile I have shown and described certain flanges a, in this case, may be ,metallic runners fitted in specific arrangements for retaining the runners, obviously changes can hemade in the attaching means, within the scope of the skilled mechanic without spirit of my invention.

I claim: 1 V7 v 1 1. A rectangular crate of the character described, having wooden side and end pan the side panels beels, the bottom edges of ing provided with longitudinal grooves,

the grooves adapted to project above'thebottom surface of the panels, and means for securing the ends of the, runners to said panels.

2. A rectangular crate of the character described having wooden side'and end panels,-the bottom ing provided With longitudinal grooves terminating with upwardly extending sockets, disposed at acute anglesto the grooves and metallic runners partially embedded into the grooves having upturned ends nested in the sockets under tension.
